06 XC70 Suspension refresh torque values please.

Post by scot850 » Sat Jun 09, 2018 12:47 pm

I am in the process of re-building the front 4-C suspension for my sons' 06 XC70. I have read and re-read the torque info in Vida several times. Unlike the older models in Vida, where they give the value of a bolt or nut torque at the point in the description, for the P2's they send you to a master list. It looks like a British person (I am British) wrote it who had no idea what they were saying. Some of it makes no clear sense.

I think I have now got most of the values figured out, with the exception of 2:

1) Axle end bolt in the hub - I have found 3 possible options for this but with one being 100Nm that I would think is too high for that bolt. The 00 P80's use the same bolt and it is something like 35Nm + and 90 degree angle torque

2) The nut on the outer Tie-rod to the steering arm on the hub assembly. Again various values up to 100Nm.

Can anyone clarify for me what these 2 values should actually be?

Thanks,

Neil.

I'd use this S60 list, while the suspension on XC70 is more robust, it's still not a XC90 so the values for S60 may be close.

http://www.volvohowto.com/volvo-s60-v70 ... fications/

14mm axle one Bolt drive shaft – wheel hub, front the one with the 90deg rotation. Sometimes it gets grease on the threads as it goes right into the CV joint which doesn't help measuring the correct torque

Tie rod end to the spindle (70 Nm) it's quite a bit higher as it's a stretch .. nut. I've read it's a single use nut.

Since they're all P2s there shouldn't be much difference. The XC90 isn't a more robust car than the S60. It's just heavier so it wears the suspension parts out faster.. :-P

The drive bolt for the outer end of the axle is a 13mm on our car (new bolts from Volvo).

The tie-rod is listed as best as I can see on 3 different sources would now appear to be 100Nm for the ball-joint to the steering arm on the hub.

I can always re-check the hub axle bolt with the dealer on Monday, but for now I will use the same values as my 00 P80 'R' of 35Nm + 90 degrees.

Thanks for helping guys.

Neil.

I had both, 13mm and 14mm. I think the shaft part of the bolt is the same, only the head changed size (from some reason, not the first bolt I see that changed head size, same went for the bolts that keep the ignition coils in place)

As for the tie rod end to the hub nut, in doubt I'd ask a Volvo technician. This nut/ball joint is quite important, when looking at the way the ball joint of the tie rod goes into the hub, Volvo changed it to insert from the bottom up, which is the opposite of the older design on P80 which was a fail safe design. On P2 if this nut breaks loose for some reason, the ball joint can drop from there.. however the nut is a crushed type (oval design) meant not to turn that easily.

I have figured it out by looking at different areas of Vida and on line.

1) The tie rod ball joint to steering arm on the hub assembly is 100Nm.

2) The hub to axle bolt is the same as the P80 later version of 35Nm + 90 degrees.

I have now built up the LHS except for connecting the 4-C cable back in. Tomorrow hope to complete the RHS, refit the under tray and refit the wheels.

Thanks for the help guys.

Neil.
